Description
Technical field
The present invention relates to a kind of for Motor Vehicle automatically or the hydraulic supply unit of the speed changer of automation, especially dual-clutch transmission, it has
-high tension loop, this high tension loop has accumulator and supplies by high-pressure service pump;
-low tension loop, this low tension loop supplies by low pressure pump, and wherein said high-pressure service pump and described low pressure pump are driven by common driver element;
-be arranged in the valve in described high-pressure service pump downstream, this valve has at least two switching position, the supply that wherein can realize for described high tension loop by described high-pressure service pump in first switching position, and described in second switch position, the outlet side of high-pressure service pump is connected with container or is connected with the suction side of described high-pressure service pump.
Background technique
That disclose vehicle transmission by the document EP1420185A2 forming described type, that there is high tension loop and low tension loop hydraulic supply unit, wherein by pump to each loop delivering fluids.Two pumps is driven by common driver element simultaneously.In each loop, arrange valve in the downstream of every platform pump, described valve has two switching position.In first switching position, described delivery side of pump side be connected with affiliated pressure circuit and described pump to described pressure circuit delivering fluids.If there is fluid demand and there is not fluid demand or enough pressure in another pressure circuit in a pressure circuit, so do not require that the valve in the pressure circuit of fluid is moved in its second switch position described.In described second switch position, described delivery side of pump side is connected with its suction side, and described pump runs thus and do not transport fluid in this pressure circuit in idle running.The energy ezpenditure of this pump declines and than much smaller when described pump must extrude superfluous fluid by pressure-limit valve thus.Implement flexible programs for two kinds of connection on disclose described valve and described pressure circuit fluid technique.In the first flexible program, the pressure circuit belonging in described second switch position also with the suction side of described pump in other words described container be connected.This causes following result: in this switching position, this pressure circuit to be switched in the state of fully pressure-free power and its pump must form described pressure again when there is pressure demand.Must connect described pump very continually and for a long time thus, this causes higher energy ezpenditure.
In described second flexible program, in the second switch position of described valve, affiliated pressure circuit and described delivery side of pump side cut off.Pressure is maintained in this pressure circuit, until its fluid consuming due to described load does not drop under threshold value.Then then must reclose described pump.The shortcoming of this flexible program is, it does not have the pressure drop that can realize being controlled in described pressure circuit.Especially the pressure obtaining maintaining in high tension loop then can be harmful to valve after the described Motor Vehicle that stops for the valve no longer moved in this pressure circuit.The similar layout of described valve also obtains open from DE102010018192A1, and wherein here described high tension loop is equipped with accumulator.Shorten the time of delivery of necessity of pump thus, but describe mentioned shortcoming simultaneously, because pressure acts on described valve for a long time with higher level.
Summary of the invention
Therefore task of the present invention is, so improves a kind of hydraulic supply unit with high tension loop and low tension loop, make its loss few and have efficiency, and it can realize pressure drop targetedly in described high tension loop.
This task is resolved in the following manner in conjunction with the preamble of claim 1: described valve has the 3rd switching position, and described in described 3rd switching position, high tension loop is connected with described container.According to demand, typically after the Motor Vehicle that stops, described valve can be switched in this switching position, can reduce the pressure in described high tension loop thus.Thus the valve in described high tension loop and other component unloaded and extend its working life.Do not need extra valve, simple, the with low cost and impact that is not easily interfered of described device thus.Generally supply final controlling element by described pressure duct, described final controlling element handles one or more clutch and shifting cylinder.If desired, described valve also can be used as safety valve, in the process run at Motor Vehicle in urgency by described safety valve when modulating valve is malfunctioning by emptying for described high tension loop, thus be such as separated described Power Train when clutch initiatively closes.
